    • A 3-dimensional image is obtained from a 2-dimensional display by varying the apparent distance of the image from the viewer on a pixel by pixel basis. This can be done by positioning an array of pixel-level optical elements in alignment with the pixels in the image. In a preferred format, each of the optical elements is generally elongate and has a focal length which varies along its length with the result that the point along its length at which light enters the optical element determines the apparent visual distance of the associated pixel from the viewer. In the case of a cathode-ray tube application, controlling the position of entry of the light is done by controlling the electron beam to move a minute distance vertically as it scans horizontally. In a television application, the vertical distance may be determined by a depth component incorporated in the broadcast signal received by a television set. Applications and embodiments relating to computer monitors, film and still printed imagery are also described. Specifically there is provided a method of retrofitting 3-D information to conventional 2-D imaging, comprising the step of digitizing each scene, defining individual objects in the scene, assigning a specified depth to each object in the scene, scanning each pixel in the scene and assigning respective depth components to the pixels according to the specified depth.
    • 通过逐像素地改变来自观看者的图像的表观距离,从二维显示获得三维图像。 这可以通过将像素级光学元件的阵列与图像中的像素对准来实现。 在优选的格式中,每个光学元件通常是细长的并且具有沿着其长度变化的焦距,结果是沿着其进入光学元件的长度的点确定相关联的像素的视觉距离 观众。 在阴极射线管应用的情况下,通过控制电子束在水平扫描时垂直移动微小距离来控制光的入射位置。 在电视应用中,垂直距离可以由并入由电视机接收的广播信号中的深度分量来确定。 还描述了与计算机监视器,电影和静止打印图像有关的应用和实施例。 具体地说,提供了一种将3-D信息改造成常规2-D成像的方法,包括对场景进行数字化,定义场景中的各个物体的步骤,为场景中的每个物体分配指定深度的步骤,扫描场景中的每个像素 并根据指定的深度将各个深度分量分配给像素。

    • Three-dimensional imagery based on a series of two-dimensional images is produced and displayed. A frame (20) housing a series of image displays (22) displaced at differing radial distances from the center (39) of the frame is rotated at 60 hertz or greater. As each display rotates past the viewer, a different sectional slice of a three-dimensional image is displayed. Thus, a full rotation of the frame provides the viewer with a full view of the three-dimensional object. The high rotational speed of the system visually merges the slices and the radial displacement of the displays provides depth to the image. This combination results in the presentation of a true three-dimensional image without the need for viewing aids. Additionally, multiple viewers can view the same or differing three-dimensional images.
    • 产生并显示基于一系列二维图像的三维图像。 容纳从框架的中心(39)以不同径向距离移位的一系列图像显示器(22)的框架(20)以60赫兹或更大的速度旋转。 随着每个显示器旋转经过观察者,显示三维图像的不同截面切片。 因此,框架的完整旋转为观看者提供了三维对象的完整视图。 系统的高旋转速度在视觉上合并切片并且显示器的径向位移为图像提供深度。 这种组合导致无需查看辅助设备而呈现真实的三维图像。 另外,多个观看者可以观看相同或不同的三维图像。

Date Oct. 10, 1996The present invention relates to improvements in a three-dimensional display system. A transformation technique is described wherein deflection coordinates defining the spatial locations of the images written into the display volume are determined by transformation from a coordinate system based on the display volume to a coordinate system based on the one or more electron guns. The application further relates to a technique by which the location of an electron beam within the display volume may be determined. These techniques involve positioning conductive material at various locations such as the screen and the enclosure of the display itself so that the impinging electron beam may be detected and thy the location of the beam in the display volume may be derived. Image enhancing techniques are described in conjunction with the location techniques whereby conductive films are evaporated onto the screen and/or the enclosure. Modifications in voxel plotting techniques are described so as to enhance the quality of the image produced in the display volume. The technique includes interlacing the scanned print location. An additional improvement is provided by a particular conduction medium configuration superimposed or deposited onto the screen where the conducting medium incorporates information which is extracted or read from the medium by scanning a particle beam across its face so as to invoke momentary voltages or currents in the conducting medium.
